alright heres the big question between the red rtv, the grey rtv, 3m weatherstrip adhesive and the spray gasket which worked pretty well on my trans pan by the way; what should be used for what application? and what have you guys used succesfully and would continue using. i have to do my engine oil pan gasket, rearend gasket, and valve cover gaskets. (if possible list whatever you guys have used for anything i guess, for future knowledge) and lastly any extra comments you have about the spray gasket and its applications would be appreciated , it seems to be the most user freindly and id like to know what else i can use it for.


Thanks alot guys

 

machined surfaces usually needs nothing. i like very thin layer of ultracopper rtv on any pan. i use high tack to stick anythnig in place i don't want moving, pst on any fastener going to water, k&w copper in spray can on head and long intake gaskets, also use permatex copper sealer in brush top can for a few gaskets, any rtv i use is ultracopper
